Good sowing days

17 days

The moon passes through all twelve signs of the zodiac each month, and biodynamic growers match what they sow to the element the moon is travelling through. In May 2027 the moon is ascending — the traditional time for sowing and grafting — on 18 days. The strongest sowing dates fall on the 1, 2, 3 and 14 other days. Days marked in the table below sit near a lunar node or perigee, when traditional practice is to leave the soil alone.
